In this article, we defined comprehensive recommendations for the clinical follow-up of pregnant women with a malignancy-suspicious NIPT result, on the basis of the vast experience with population-based NIPT screening programs in two European countries complemented with published large data sets. These recommendations provide a tool for classifying NIPT results as malignancy-suspicious, and guide health care professionals in structured clinical decision making for the diagnostic process of pregnant women who receive such a malignancy-suspicious NIPT result.

The SETD2‐related overgrowth syndrome is also called “Luscan‐Lumish syndrome” (OMIM 616831) with the clinical characteristics of intellectual disability, speech delay, macrocephaly, facial dysmorphism, and autism spectrum disorders. We report on two novel patients a 4.5‐year‐old boy and a 23‐year‐old female adolescent with a speech and language developmental delay, autism spectrum disorder and macrocephaly, who were both diagnosed with SETD2‐related overgrowth syndrome due to de novo frameshift mutations in the SETD2 gene. Features not previously described which were present in either one of our patients were nasal polyps, a large tongue with creases, a high pain threshold, constipation, and undescended testicles. These features may be related to the syndrome and may need special attention in future patients. Additionally, prevention of obesity should be an important point of attention for patients diagnosed with a SETD2‐related overgrowth syndrome.
